Why is concave mirror used in Searchlight & head lights? When the bulb of headlight is placed at focus of concave mirror, it allows the light to spread out to infinity (longer distances) and at infinity they are approximately parallel. Hence, concave mirrors are used in the headlights of vehicles. What is the role of […]
Why CSMA CA is used for wired network?
Why CSMA CA is used for wired network? CSMA/CA tries to reduce the frequency of these collisions and provide a plan at the same time on how to proceed if a collision does occur. The protocol is also important because the transmissions in the wireless networks cannot run in the same order (due to the […]
Is almond milk OK on Mediterranean diet?
Is almond milk OK on Mediterranean diet? Milk is not traditionally part of a Mediterranean diet. If you’re new to this way of eating and are struggling to cut down your dairy, you can substitute it with unsweetened almond or soy milk, since nuts and legumes are staples of the diet. Is peanut butter OK […]
What is a lowest energy?
What is a lowest energy? These zones are known as energy levels (or sometimes called electron shells). At the lowest energy level, the one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons. At the next energy level, there are four orbitals; a 2s, 2p1, 2p2, and a […]
Which metal is used to make car bodies?
Which metal is used to make car bodies? The main materials used for making cars, parts and components, along with future trends, are steel, aluminum, magnesium, copper, plastics and carbon fibers. The prime reason for using steel in the body structure is its inherent capability to absorb impact energy in a crash situation. What is […]
What are some long term consequences of desertification?
What are some long term consequences of desertification? Desertification reduces the ability of land to support life, affecting wild species, domestic animals, agricultural crops and people. The reduction in plant cover that accompanies desertification leads to accelerated soil erosion by wind and water. How can we reduce land degradation? 5 possible solutions to soil degradation […]
What are the major steps in homeostasis?
What are the major steps in homeostasis? Adjustment of physiological systems within the body is called homeostatic regulation, which involves three parts or mechanisms: (1) the receptor, (2) the control center, and (3) the effector. The receptor receives information that something in the environment is changing. What happens to the body after exercise homeostasis? To […]
What causes the temp to decrease with height in the mesosphere?
What causes the temp to decrease with height in the mesosphere? Within the mesosphere, temperature decreases with increasing height, due to decreasing absorption of solar radiation by the rarefied atmosphere and increasing cooling by CO2 radiative emission. The top of the mesosphere, called the mesopause, is the coldest part of Earth’s atmosphere. Does temperature increase […]
Why does a balloon move in different directions?
